Class CurveTo

com.datalogics.PDFL.CurveTo

public class CurveTo
extends Segment

The curveto operator is used to draw a Bezier curve. The curved segment is appended to a path.

The curveto operator calculates the curve between two endpoints, the current (beginning) point and the final (end) point, and in relation to two matching control points.

The control points define the nature of the curve between the two endpoints. These values are represented by a series of x and y coordinates.

Constructor and Description
CurveTo(double x1, double y1, double x2, double y2, double x3, double y3) Append a cubic Bézier curve to the current path. The curve extends from the current point to the point (x3, y3), using (x1, y1) and (x2, y2) as the Bézier control points. The new current point is (x3 , y3).
CurveTo(Point point1, Point point2, Point point3) Append a cubic Bézier curve to the current path. The curve extends from the current point to point3, using point1 and point2 as the Bézier control points. The new current point is point3.

Constructor Detail

CurveTo

public CurveTo(Point point1,
               Point point2,
               Point point3)

Append a cubic Bézier curve to the current path. The curve extends from the current point to point3, using point1 and point2 as the Bézier control points. The new current point is point3.

Parameters:

point1 - the first control point.

point2 - the second control point.

point3 - the new current point.

CurveTo

public CurveTo(double x1,
               double y1,
               double x2,
               double y2,
               double x3,
               double y3)

Append a cubic Bézier curve to the current path. The curve extends from the current point to the point (x3, y3), using (x1, y1) and (x2, y2) as the Bézier control points. The new current point is (x3 , y3).

Parameters:

x1 - The x-coordinate of the first control point.

y1 - The y-coordinate of the first control point.

x2 - The x-coordinate of the second control point.

y2 - The y-coordinate of the second control point.

x3 - The x-coordinate of the new current point.

y3 - The y-coordinate of the new current point.
